ABSTRACT:
Low water silicone-containing elastomers are based on a hydroxy- or amino-terminated prepolymer derived from an ethylenically unsaturated silicon-containing monomer, and at least one monomer reactive with hydroxyl- or amino-functional radicals of the prepolymer. The elastomers are especially useful as contact lens materials.
